The conclusion can not be deduced from the chart above. It’s a boxplot and one can only see the trend is everyone becomes more depressed. But how many cannot be deduced. The width of boxplot is shorter in 2017 when compared to 2016, meaning the elderly were having closer scores when compared to each other. Everyone is more depressed overall. The first Quartile of people was scored 1-10 but now the first Quartile of people was scored 7-13. However, we didn’t know if those were the same people. It could be someone with a score of 15 in 2016 dropped to a score of 5 in 2017. So the 10% increase is not seen from the boxplot.
2016 range:1-25
2016 medium: 13?
2017 range: 7-26? With one outlier who has an extreme high score
2017 medium: 15
From the medium, a logical conclusion is everyone is more depressed.
All numbers above are just estimates from the boxplots given
